Hey,
Don't be shy. You have a question, something you are struggling with, ...?
Or maybe you want to travel and would like to have some tips for Europe, Australia, New Zealand,...
I helped many Japanese persons during my travels and while being in my home country. So I'm sure I'll be able to help you.
If you want to learn Dutch (a language that isn't in the list). As native speaker you are more then welcome.
Let me know if you are interested ^,^
